Be it known that I, FRANK Somer, a citi- Zen of the United States,residingin Philadelphia, Pennsylvania, have invented certainImproven'ients in Chain Locks, of which the following is aspecification. n K VOne object of my invention is to provide a padlockwith a shackle in the form of` a chain and to providemeans for securingthe loose end of the chain to the lock casing at any point desired.

.A further ob 'ect ofthe invention is to provide a bolt which can bepushed into engagement wit-ha chain by hand, 'but which must beretracted by the mechanism within the lock. j l l A still further objectof the invention is to construct a chain lock in such a ymanner that thelock casingand the mechanism may be made standard, and the keeper havingva channel for the passage of the free end of the chain canbe made ofdifferent sizes to fitdifferent types of chain and can be attached to astandard casing.v y In the accompanying drawings; n'

Referring to Figs. 1 to 8 of the drawings, 1 is the casing of the lockmade in two parts in the usual manner. Located within the casing is abolt 2 actuated by mechanism .which will be' described hereinafter. 3 isa types.

chain, whichmay be. of any of the usual has a body portion locatedwithin the casing. This .body portion isperforatedffor the passage .ofthe pin 5.k The lockcasing vmay be cutaway? to receive the clipsothatthe clip will beheld rigidly in position.

Secured to one side ofthe casing in line 6, in the present' instance, issecured tothe casing of the lock by rive-ts 7, which are preferablyco-untersunk, as shown, but other means of fastening maybe used ifrfound more des1rab'le.

The chain is secured to the casing, `1n the presenty instance, by vaclip 4, which When the bolt 2 is projected, vit extends i into thechannel and. passes through `one of theflinks of the chain', as clearlyshown in Figs. 2 and 3, locking the chain firmly to the casing.v Thelocking mechanism .con`

sists of a latch 8, 6 pivotally mounted `on the pin 5, an actuatingplate 9,and one or more tumblers 10, pivotally mounted on vthe pin 11.Each tumbler has the usual l.spring 12 and is notched to receive thestump 113 carried by the .actuating plate 9. yThere may be asmany of thetumblers as .desired and the notches in the tumblers will be indifferentpositions, according to the, combination desired.

",'The bolt is notched at 141 to receive the projection 15' ofl thelatch. hen theprojectionv vis in the notch 111, it prevents vthewithdrawal. of the bolt. It is held in the notch by. aspring 16. 'On`the latchl is a projectionf17, which extends into a recess in the plate9 so that, kwhen the plate is shifted in the 'direction `of the arrow(Fig.

v7) by the key, it turns the latch on its pivot and vforces theprojections 15 out of the notch 14,' freeing v the bolt, which is forcedback by a spring 19 that bears against4 the pin 2O on the bolt, lthespring being j pivotally mounted on the pin 21 of the'casing. The plate9 is slotted at 22, 22, so

that it will slide upon the pins 24 and 11..y

In the presentv instance, the stump 18 has an extension 13a, ,whichvprojects over the free ends" of the tumblers, keeping them in positionon the pivot pin-11.

It will be .seen bythe above construction that the bolt iS free to bemanually pressed into engagement With the chain and, when in engagement,the latch Willjei'rterthe notch in the bolt, holding it in its locked'position against the pressure of the spring 19. When it is desi-red torelease the bolt, a key is ifn- .serted in the key post 25 and turned soas to Cause `the tumbler to align With the stump of the actuating plate.On the continued movement of the key, the plate Will be shifted and Willmove the latch out of engagement with the bolt, allowing the bolt to beWithdrawn by the spring 1'9, thus freeing the chain. A lug 26 'on thebolt lcomes in contact With the pin 24 so as to limit the Withdrawalmovement of the bolt. The chain can be of any length ydesired,accordi-'ng to the usetor Which the lock is intended.

In Figs. 9 and l0, the keeper l6 is 'shown separated from the lockcasing 1. By making the keeper separate from the casing ,a standardl'oc'k casing can be 'assembled With any size -or type `olke'eperdesired, depending, somewhat, on the character and. size ot the chain. j

In Fig. Il, a light, narrow chain is illustrated `and in Fig. 12 anothertype 'of "chain is shown. The keeper must be of su'chs'ize as to holdthe chain properly When the bo'lt is projected.

In Fig. l1, a pivoted plate 9a stead of a Isliding plate. This pivotedplate 9 has a key stump i3d and is so shaped as to be actuated by 'thekey. As it turns on the pivot, it will raise the latch 82L out ofengagement With the bolt 2, and, on the continued movement of 'the key,it will come in contact with the short arm ot' the lever, whichactua-tes the bolt so as to' retract 'the bolt by lthe key instead of bya spring, as in Fig. 2.

The construction may be modified, as in Fig. 2, in which `the pivotedlatch 8b engages the bolt 2b and is actuated by the key. Vards 27 may belocated on the pins, as shown.

I claim:

1. vThe combination of a casing; a 'chain 'attached at one lend tio thecasing; a keeper at the l'side of the casing forming 'a channel for vthepassage of the free 'end of the chain;

is shown, in'- to be projected 'into the channel and into engagementwith the chain; a 'spring for retract-ing the bolt, said bolt beingnotched; a

pivoted latch having a projection adapted to the notch; an actuatingplate engaging the latch, said actuating plate carrying astump; and atumbler, the tumbler and the plate being arranged to be actuated by akey so as to Withdraw7 "the latch and allow the bolt to be retracted byits spring. A

2. The combination in a chain lock, of a two-part casing; a chain; aclip at one end of the chain, said clip being perforated; a pin in thelock casing extending through the 'pe'rforations in the clip; a keeperon the casing forming a channel for the passage of the :tree end of thechain; a sliding bolt in the casing arranged to be rojected into thechannel; a latch pivotally mounted on the pin that passes through theclip, said latch having a projection; a notch in the bolt into which theprojection extends; a spring for retracting the bolt; a slidingactuating plate carrying a stump, said plate being recessed; a secondprojection on the latch extending into the recess; and a pivoted tumblernotched to receive the stump of the plate.

43. The combination of a casing; a keeper attached thereto at one sidethereof; a chain, one end of the chain being attached to the casing andthe other end being free to pass through the keeper; a bolt in thecasing arranged to engage a portion of the chain in the keeper; a latchengaging the bolt; a sliding stump-carrying plate arranged to yactuat'ethe latch; a tumbler; and means for retracting the bolt Whenjreleased.

4. The "combination in a chain lock, of la casing; llocking mechanismtherein including a bolt; a keeper made separate from the casing andadapted to be attached thereto; means for securing the keeper to thecasing, whereby keepers of different size or shape may be attached tothe casing; and a chain, one end of which is secured to the casing andthe otherpend of Which is adapted to pass through the keeperforengagamen-t by the saidbol't. ,Y FRANK SOLEY.
